Kaido was one shotting luffy and knocked him out multiple times, Yet luffy got back up.
Every single time besides G5, when Kaido knocked Luffy down he was out and needed time or assstance before making a comeback that doesn’t say much
1st time gassing out post Kong Gatling; needed 10 minutes or so of stalling from Law, Kid, Killer, and Zoro
2nd time getting knocked out by Co3W Thunder Bagua: kid, Killer, and Law almost took out Big Mom and Zoro pulled out Asura.
3rd time: he literally almost drowned got food and a ride back to the fight while Yamato stalled.
4th time: literally died and revived by G5 while Kaido left.
This isn’t saying much tbh.
The ap difference was also as big. Luffy has been fighting against those with higher ap advantage than himself. Luffy gets stronger as he fights. His power can spike from emotions also. 3× accelerative developments. Luffy has more chance of growing far stronger than naruto especially if the battle draws out.
Luffy grows while a battle gets stronger assuming he isn’t knocked out or gassed first, Naruto always has the option to get stronger via more nature energy. One is a more readily accessible amp.
Luffy has evaded fatal blows for 13hrs against katakuri.
Katakuri is a tickle monster without his spear.
His body can also instinctively move on its own to avoid fatal blows. Pretty sure haki emission can deflect/defend against tso.
They can’t that’s very arguable if we’re being generous.
G5 turns it into rubber etc.
He’d be erased in constant why would turning it into a rubber ball of death change anything?
If theres no argument for naruto beating luffy in the 1st 30m-1hr then game over because luffy most likley be on his way to power spiking near nardos lvl.
And Naruto uses Boil Release or Nature energy to get even stronger.
How would naruto even manage against luffy's unpredictable fighting style? Naruto all he does is use his clones for trickery but it wont work on luffy due to coO as i said before.
Do we even know is Kenbun would be able to sus out the real Naruto given they all have minds a life force, and are pieces of the real Naruto (like a clone of Naruto having a soul to soul convo with Kurama when they first met Madara)
So what else does he have? Tso can be defended against.

bijuu spam and that can be reflected.
None of that is getting reflected with a 2x to 6x gap that can grow with more amps
